Application filed October 31, 1921. Serial No. 511,731.

T all whom it may concern- Be it known that I, GEORGE P. RAsoK, acitizen of the United States of America, and resident of Des Moines,Polk County, Iowa, have invented a new and useful Threshold WeatherStrip, of which the tollowing is a specification.

An object of this invention is to provide an improved weather-stripadapted to, be attached to the lower marginal portion of a hinged doorand to be pressed into close sealing engagementwith the threshold whenthe door is closed.

A further object of this invention is to provide an improved thresholdweatherstrip for hinged doors adapted to engage guides on the doorcasing and be forced by said guides into sealing engagement with thethreshold as the door is closed.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which- Figure 1 is aperspective view showing a portion of a door casing and door equippedwith my improvement. Figure 2 is an end elevation of the weather-stripattached to a door, shown in two dilferent positions, the thresholdbeing shown in cross-section.

In the construction and mounting of the device as shown the numerals 10,11 designate jambs of a door casing, 12 a door hinged to the jamb 11 andadapted to close against stops 13, 14;, and the numeral 15 is athreshold, all of which may be of any suitable type and construction,and are here shown conventionally.

A strip 16, of suitable sheet metal and of a length correspondingsubstantially to the width of the door, is fixed to the lower portion ofthe door, as by screws 17 in a hori zontal row, and is mounted on thatface of the door which contacts the stops 13, 14:.

as The screws 17 are arranged along the upper margin of the strip 16 andare spaced from the lower margin of the door a suitable'dist ance topermit the action of the strip hereinafter explained. The strip 16 isformed at its lower margin with a reeurved loop 18 extending from end toend thereof, projecting away from the door in substantially a horizontalplane near the lower margin of the door, and having its opening directedtoward the door. formed with a rib or angular bead '19 extending fromend to end thereof and spaced a short distance below the row offasteners The strip 16, is also 17, and said rib or head is so formedthat i extending from end to end of the recurve loop 18 of the metalstrip. The loop 18 may be formed with dents or depressions 21 atintervals to retain the compression strip in place. The head of theT-shaped compression strip 20 lies in a plane just behind the metalstrip 16, and is adapted at times to contact with the adjacent face ofthe door 12 along its lower margin; and said head is also adapted tocontact, at its lower margin, with the upper face of the threshold 15,as shown by solid lines in Figure 2, therebyeil'ectually closing andsealing any crack which might otherwise exist between the lower marginof the door and the threshold. Curved guides 22, 23 are fixed to lowerend portions of the stops 13, 14 or jarnb members and project outwardlyfrom the faces thereof just above the threshold 15.

The lower faces of the guides 22, 28 are of convex curvature and are soarranged that, in the process of closing the door, they are engaged bythe outer edge of therecurved flange or loop 18, and continued closingmovement of the door causes said loop, and with it the lower portion ofthe metallic strip to be pressed toward the adjacent face oi the door.Such movement also exerts a downward pressure on the loop 18 andcompression strip 20, and when the door has arrived at its fully closedpositionsuch pressure causes the compression strip to T011111 a seal forthe joint between the lower n'iargin of the door and upper face of thethreshold which excludes all drafts aswell as moisture from without. Theguides 22, 23 not only serve to guide the loop and compression strip totheir sealing position, but hold them in such position so long as thedoor is closed, as shown clearly by the solid lines in Figure 2, themetal strip, recurved loop and compression strip. being under tensaidmetallic strip being resilient and normally standing atan angle awayfrom the door, saidmetallic stripbeing formed at its lower'margin with a'recurved loop opening toward the door, a compression strip sub- I,srm'mau T-shaped in cross-section having its leg flange mounted in saidloop and its head directed toward the door, and curved guides carried bythe door casing and adapted tobeengaged by end portions of said loopwhenthe door'is closed, and said guides be ing so curved andthewveatherstrip so posiv tioned on the doo-rthat the head of thecornpression strip is forced against the door and also against thethreshold when the door is closed. r

- 2. In a weather-strip, a resilient metallic strip adapted to besecured at onernargin to the outer face of a door transversely of thelowerportion thereof, said metallic strip being formed with alongitudinal bead or rib adjacent its upper margin forming an integralhinge, said metallic strip also being formed with rec-urved loop at itslower marg n opening 'toward the outer face of the door, and acompression strip of flex ble and compressible material, formedsubstantially. T-shaped in cross-section and haying one flange proect1ng and secured with n said recurved loop, the head ofsaidcompression strip being adapted to engage at times with theouter face ofthe door and extend below the edge thereof whereby it also isa dapted toengageathreshold below said door.
